PTO Switch
The PTO switch is used to engage or disengage the cut- ting deck. The PTO switch is attached to the control con- sole next to the operator seat (Fig. 17).
The switch terminals are marked as shown in Figure 18. The circuitry of the PTO switch is shown in the chart be- low. With the use of a multimeter (ohms setting), the switch functions may be tested to determine whether continuity exists between the various terminals for each position. Verify continuity between switch terminals.
NOTE: The PTO ENGAGE position requires lifting and pushing the lever toward the switch keyway. The PTO OFF position occurs when the lever is pushed opposite the keyway.

The switch terminals are shown in Figure 20. The circuit- ry of the switches is shown in the chart below. With the use of a multimeter (ohms setting), the switch functions may be tested to determine whether continuity exists between the various terminals for each position. Verify continuity between switch terminals.
